Punctuation marks are the traffic signals of writing. They tell the reader where to pause, stop, or pay attention, and they can completely change meaning. Compare: “Let’s eat, Grandma!” and “Let’s eat Grandma!” This guide explains the main punctuation marks in English and how to use them.
How Many Punctuation Marks Are There?
Most guides list about 14 common punctuation marks in English: the full stop (period), comma, question mark, exclamation mark, colon, semicolon, apostrophe, quotation marks, hyphen, dash, parentheses (brackets), square brackets, ellipsis and slash. You will use the first eight most often.
Full Stop / Period ( . )
Ends a statement: The class starts at nine. Also used in some abbreviations: Dr., etc. (“Full stop” is British English; “period” is American English.)
Comma ( , )
- Lists: I bought rice, lentils, and onions. (The comma before “and” is called the Oxford comma; it is optional in British English but common in American English.)
- Before a conjunction joining two full sentences: It was raining, so we stayed inside.
- After introductory words or clauses: However, the plan worked. When I got home, I slept.
- Around extra information: My brother, who lives in Chittagong, is a doctor.
- Not to join two full sentences on its own (a comma splice): ❌ I was tired, I went to bed.
Question Mark ( ? ) and Exclamation Mark ( ! )
A question mark ends a direct question: Where are you going? Indirect questions take a full stop: She asked where I was going. An exclamation mark shows strong feeling: What a great idea! Use it sparingly in formal writing.
Apostrophe ( ‘ )
- Contractions: don’t, it’s (it is), I’m.
- Possession: Rahim’s book (one owner), the students’ books (plural owners ending in s), the children’s toys (irregular plural).
- Not for ordinary plurals: ❌ apple’s for sale ✅ apples for sale.
Colon ( : )
Introduces a list, explanation or quotation after a complete sentence: You need three things: a pen, paper and patience.
Semicolon ( ; )
Joins two closely related complete sentences: I love reading; my sister prefers music. It can also separate list items that already contain commas.
Quotation Marks ( ” ” or ‘ ‘ )
Show someone’s exact words or titles of short works: She said, “I’ll be late.” American English usually uses double quotation marks; British English often uses single ones.
Hyphen ( – ) and Dash ( – or — )
A hyphen joins words: well-known, a five-year plan. A dash, which is longer, adds a pause or emphasis: She had one goal – to win.
Parentheses ( ) and Ellipsis ( … )
Parentheses add extra information: The test (worth 20%) is on Friday. An ellipsis shows missing words or a trailing thought: I was going to say…
